Mini-drip sets deliver at a rate of 60 drops per milliliter. They can often be identified by the small, metal tube inside the drip chamber, although manufacturers conceal this tube in the upper end of the chamber. There may also be the number "60" stamped on one of the 'wings' at the top of the chamber, indicating that it is a 60 drop/ml administration set.

Because of their low flow rates, mini-drips are well suited for precise medication administration where a medication is injected into the IV bag, then infused via IV drip over an extended period of time. Since a mini-drip set needs 60 drops to deliver 1 ml of fluid, the KVO flow rate would be 1 drop every second to deliver 1ml/minute.
